I had the pleasure of visiting the Museum near Melbourne when my son lived there. It is an excellent day out but at the time of my visit it was not possible to look over the C 130A . However inside the museum they had a full size photo of FS245 with some of the para seats fitted in front of it. It seemed quite realistic.
Although the 'A' was the real forerunner of all subsequent Hercs it does differ in several major respects. Some differences are obvious like the three bladed props others like the electrical and hydraulic system for example are not.
